특정 테이블에서 데이터를 조회합니다 (제한된 행 반환).
AI agents call query_table to retrieve information from MariaDB Reader MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a MariaDB table without modification or deletion. The explicit mention of limited row returns mitigates risk by preventing bulk data exfiltration. Combined with sibling tools (get_table_schema, list_databases, list_tables) that are all schema-inspection utilities, query_table is clearly a read-only operation. No code execution, data modification, or irreversible actions are involved.
From the tool's definition Tool description states '특정 테이블에서 데이터를 조회합니다 (제한된 행 반환)' which translates to 'Query data from a specific table (returns limited rows)'. The term '조회' (query/retrieve) indicates read-only data retrieval with row limits preventing excessive data extraction.
Attacks that exploit this kind of access
특정 테이블에서 데이터를 조회합니다 (제한된 행 반환). It is categorised as a Read tool in the MariaDB Reader MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MariaDB Reader MCP Server MCP server in PolicyLayer and add a rule for query_table: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MariaDB Reader MCP Server. Nothing to install.
query_table is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the query_table rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for query_table. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
query_table is provided by the MariaDB Reader MCP Server MCP server (moosin76/mcp_server_mariadb_reader). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
